| abstract | 【Task】 Provided is a method for producing an optical film that reduces quality defects such as creases caused by wrinkles inside an optical film roll that occurs during winding or over time when a stretched optical film is produced, and has high productivity. [Solution] In a method for producing an optical film, which is molded using a thermoplastic resin containing a specific acrylic polymer and obtained through a stretching process and a winding process, the film is wound at a speed of 10 m / min to 200 m / min while pressing the optical film. It has been found that the above-mentioned problems can be solved by using a winder having a touch roll that can be wound at a speed and performing a winding process in which the temperature of the touch roll is adjusted to 3 ° C. or higher and 15 ° C. or lower.
